Gray water, or sullage, is wastewater from daily human activities that can be recycled and reintroduced into the environment to reduce freshwater consumption and promote plant growth. It is safer than chemically treated water and can only be recycled within 24 hours. Biodegradable soaps and proper system configuration are important for safe reuse.
Sullage is a term used to describe wastewater that arises as a byproduct of daily human activities such as showering, washing dishes, and laundry. It is also commonly referred to as gray water. Much of this gray water can be recycled and reintroduced into the environment instead of simply being disposed of. Environmental experts have said that gray water reuse will have a large beneficial impact on fresh water supplies over time.
Wastewater is a generic term used to describe all liquid waste, treated and untreated. The term can be further broken down into the two categories of sullage, better known as gray water, and effluent, better known as black water. Sullage, or gray water, is a mixture of water, soap, detergent, bleach, dirt, and other compounds discarded after use. Effluent, or black water, is a mixture of water and sewage that has undergone a treatment process. In other words, sullage is the residual water from household use, except for the toilet.
It is estimated that up to 80 percent of all domestic wastewater is in excess. Many see this as wasting water that could potentially be reused. Ecologists say reusing wastewater is not only better for the environment, but will also be vital in solving the planet’s projected water shortages. By reusing it, people can reduce freshwater consumption, replace vital nutrients in the soil, promote plant growth, and reduce the amount of chemicals used in treatment plants.
Many people are concerned about the safety of reusing sullage, but in the United States alone, millions of gray water systems have been used with no reports of disease. In fact, many experts argue that sullage reintroduced into the natural environment is cleaner than any water treated through chemical plants. That’s because topsoil naturally cleans and purifies water far better than any man-made inventions. The nutrients left over from the gray water remain in the potting soil and provide nutrition for the plant matter.
It is important to note that sullage can only be safely recycled within 24 hours. After that, the bacteria in the water will grow and become a health hazard. It is also important to ensure that biodegradable soaps and detergents are used by those intending to reuse water. The introduction of chemicals into the environment can pose an ecological risk. For safety reasons, a gray water system should be properly configured and functioning properly before the water is reused.
